<![CDATA[The increasing adoption of laminated timber products (e.g., glulam and CLT) in modern construction requires a systematic mapping of the scientific landscape to understand research trajectories, collaboration patterns, and the ongoing shift toward sustainability-related topics. This study aims to map the development of laminated timber research during 2015–2025 through bibliometric analysis, covering publication trends, dominant subject areas, leading sources, productive authors, keyword evolution, and thematic structures. Prior studies are often descriptive or limited to specific technical aspects, while large-scale, metadata-driven quantitative mapping remains relatively limited. The novelty lies in integrating quantitative analysis using RStudio with network-based science mapping using VOSviewer to provide a more comprehensive overview (trends, co-occurrence networks, thematic maps, and topic shifts). Publication data were mined from Scopus, yielding 1,875 documents (2015–2025), and then analyzed and visualized using RStudio (data cleaning, descriptive statistics, trend analysis) and VOSviewer (network, overlay, and density visualizations). The results indicate a strong growth in publications with a peak around 2023, dominance of Engineering-related contributions and structural/material-focused outlets, and a noticeable shift from mechanical-performance studies toward sustainability and environmental impact themes, highlighting opportunities for deeper cross-disciplinary integration in future research]]>

<![CDATA[High-rise building plumbing systems face increasing challenges related to hydraulic efficiency, energy consumption, and sustainable water management. This study aims to analyze the evolution of plumbing system configurations, efficiency strategies, and emerging research trends through a Systematic Literature Review and bibliometric analysis of Scopus-indexed publications from 2000–2025. The novelty of this research lies in integrating hydraulic engineering, smart building technology, IoT, and AI within a unified analytical framework focused on tropical high-rise buildings. PRISMA methodology, Bibliometrix-R, and VOSviewer were employed to evaluate 751 documents. The results reveal rapid growth in smart plumbing research, emphasizing energy optimization, digital monitoring, and AI-based water management systems.]]>

<![CDATA[The increasing global energy demand and high dependence on fossil fuels have encouraged the development of biomass-based alternative energy through briquetting technology. However, research on the structural frame design of laboratory-scale briquette press machines remains limited, particularly regarding structural strength validation using engineering analysis approaches. This study aims to design and analyze the structural strength of a hydraulic-based briquette press frame for laboratory applications. The research gap lies in the limited integration of structural analysis, safety factor evaluation, and frame optimization in small-scale briquette machines. The novelty of this study is the development of an ASTM A36-based frame using an integrative approach involving Computer Aided Design (CAD), stress analysis, buckling, and fatigue evaluation under pressure variations of 1000–1600 psi. The research method employed an experimental design and build approach combined with structural simulations and hydraulic pressure testing. The results showed that the maximum stress of 17.24 MPa remained far below the yield strength of ASTM A36 material, with a fatigue safety factor of 14.5, indicating that the structure is safe, elastic, and suitable for laboratory-scale biomass research applications]]>

<![CDATA[Indonesia’s spring-based water tourism possesses significant potential but faces challenges in unsustainable management, limited design innovation, and weak community linkages. This study aims to develop an integrated framework for Bah Tio Eco-Village, North Sumatra, by combining Biophilic Design and Eco-Village principles. Employing qualitative descriptive methods, data were collected via site observation, stakeholder interviews, and comparative analysis with regional and international cases. The framework operationalizes key biophilic patterns Visual Connection with Nature, Biomorphic Forms & Patterns, and Thermal & Airflow Variability within Eco-Village dimensions of ecological integrity, social empowerment, and mushroom-centered circular economy. Results demonstrate enhanced visitor restoration, environmental preservation, and inclusive local economic development. The novelty lies in translating biophilic spatial strategies into a place-based, spring-centered eco village model with low-impact engineering and community governance. This replicable model contributes to sustainable and regenerative water tourism in tropical agricultural landscapes.]]>

<![CDATA[Background: Occupational Health and Safety (OHS) programs are critical determinants of workforce productivity in high-risk industrial environments. Despite extensive literature on OHS, empirical evidence specifically examining its quantified effect on employee productivity in Indonesian state-owned power utilities remains scarce, constituting a significant research gap. Objective: This study investigates the simultaneous and partial effects of occupational health (X1) and occupational safety (X2) programs on employee productivity (Y) at PT PLN (Persero) Pembangkitan Sektor Belawan, Medan, Indonesia. Methods: A quantitative-associative cross-sectional design was employed. Data were collected via validated Likert-scale questionnaires from a census sample of 85 permanent employees. Multiple linear regression analysis was conducted using SPSS 21.0, supplemented by validity (Pearson r), reliability (Cronbach’s ?), and normality tests. Results: Reliability coefficients ranged from ?=0.655 to ?=0.822, confirming instrument consistency. The simultaneous F-test yielded F(2,82)=231.212 (p<0.001), explaining 84.9% of variance in productivity (R²=0.849). Occupational health exerted a dominant positive partial effect (?=0.828, t=13.412, p<0.001), while occupational safety also contributed significantly (?=0.124, t=2.016, p=0.047). Conclusion: Both OHS dimensions positively and significantly predict employee productivity, with occupational health being the stronger driver. These findings provide actionable evidence for policymakers and OHS managers in energy-sector utilities across developing economies. Novelty: This study is the first to quantify the differential dominance of occupational health over safety in predicting productivity within Indonesia’s state power-generation sector, extending OHS theory into an emerging-market context.]]>
